-/**
- * Abstract model that provides behavior for wrapping a property
- * value model and listening for changes to aspects of the *value* contained
- * by the property value model. Changes to the actual value are also monitored.
- * 
- * This is useful if you have a value that may change, but whose aspects can also
- * change in a fashion that might be of interest to the client.
- * 
- * NB: Clients will need to listen for two different change notifications: a property
- * change event will be be fired when the value changes; a state change event
- * will be fired when an aspect of the value changes.
- * 
- * Subclasses need to override two methods:
- * 
- * #engageValue_()
- *     begin listening to the appropriate aspect of the value and call
- *     #valueAspectChanged(Object) whenever the aspect changes
- * 
- * #disengageValue_()
- *     stop listening to the appropriate aspect of the value
